Types of Loft Conversions We Offer
We work with all major loft conversion types to suit different roof structures and property styles:
Dormer Loft Conversions
One of the most common types of loft conversion, a dormer extends vertically from the existing roof slope to create additional headroom and floor space. Ideal for almost all property types—including terraced, semi-detached, and detached homes—dormers can accommodate bedrooms, bathrooms, or home offices with ease. These conversions offer excellent value for money and usually fall under Permitted Development.
Mansard Loft Conversions
A mansard conversion alters the entire rear roof slope to a near-vertical angle, topped by a flat roof. While this requires more extensive structural work and planning permission, it offers the greatest increase in usable space—making it perfect for London terraces and homes in built-up areas. If you’re aiming for a full-width master suite or multiple new rooms, a mansard is the optimal choice.
Hip-to-Gable Loft Conversions
This type of conversion is well-suited to semi-detached and detached properties with sloping (hipped) roofs. By extending the hipped roof into a vertical gable, this method unlocks previously unusable space. Often combined with a rear dormer, hip-to-gable conversions provide a large, practical layout for family living or luxury bedroom suites.
Velux/Rooflight Loft Conversions
If your existing loft has sufficient head height, a Velux (rooflight) conversion can transform it into a functional room with minimal disruption. This is the least invasive and most affordable option, as it retains the existing roof shape and simply adds skylights to flood the space with natural light. Ideal for home offices, reading nooks, or guest bedrooms where structural work needs to be limited.
L-Shaped Dormer Conversions
Best suited to Victorian and Edwardian properties with rear outrigger extensions, an L-shaped dormer creates a larger, more versatile footprint by connecting two dormer structures at right angles. This type of conversion is particularly popular in London townhouses where extra living space is essential. It’s a smart choice for adding multiple rooms such as a bedroom and separate bathroom or study.
What Will It Cost?
Loft conversion costs can vary based on the type, size, and complexity of the build. As a rough guide:
- Rooflight Conversion: from £36,000
- Dormer Conversion: from £54,000
- Hip-to-Gable Conversion: from £72,000
- Mansard Conversion: from £60,000
We will always provide a transparent, detailed breakdown to help you budget with confidence.
Return on Investment
A well-executed loft conversion can add up to 20–25% to the value of your home. It’s not just about gaining space—it’s a strategic investment in your future.

We follow a structured 10-step process, starting with an initial consultation and feasibility study. From concept design and planning applications to construction and completion, our experienced team supports you every step of the way.

FAQS About Loft Conversions
Can I convert my attic into a bedroom?
Yes, converting your attic to a bedroom is one of the most popular uses for a loft conversion. It’s a cost-effective way to add extra sleeping space without building a full house extension. Depending on the size of your loft, you can even include an ensuite bathroom and built-in wardrobes for added convenience.
Is it possible to convert my attic into a home office?
Absolutely. Converting your attic to an office is an ideal solution for those working remotely or needing a quiet, private space at home. With careful design, we can ensure your loft office receives natural light, is well-ventilated, and has plenty of storage—creating a productive and comfortable working environment.
Should I consider a house extension instead of a loft conversion?
It depends on your needs and available space. A loft conversion makes use of your existing roof space, which is often more cost-effective than a house extension that alters your footprint. However, if you need ground-floor living areas—such as a larger kitchen or open-plan space—an extension might be more suitable. We offer both services and can advise on the best option during your initial consultation.
Is a loft conversion classed as an upstairs extension?
Yes, many people refer to a loft conversion as an upstairs extension because it adds a new storey of usable living space. Unlike traditional extensions, it builds upward into the roof space rather than outwards—making it ideal for homes with limited external space.
Will I need a Party Wall Agreement?
If your property is semi-detached or terraced, and the loft conversion work affects a shared wall, then yes—you will likely need a Party Wall Agreement. This is a legal requirement under the Party Wall etc. Act 1996. We can guide you through the process and ensure your neighbours are properly notified and all formalities are handled professionally.
Do I need planning permission for a loft conversion?
Most loft conversions fall under Permitted Development Rights and do not require full planning permission—provided the design meets certain conditions (such as volume limits and no major alterations to the roofline). However, homes in conservation areas or those making significant changes may need permission. Our architectural team will assess your project and manage any necessary planning applications.
What are Building Control inspections, and are they required?
Yes, Building Control inspections are a legal requirement for any structural works, including loft conversions. These inspections ensure that the build complies with safety standards around structure, fire protection, insulation, ventilation, and access. At Aura, we work closely with Building Control from the outset and ensure all work is certified upon completion.
